Description

Technical Field

[0001] The invention relates to the field of cooking devices, and in particular to an integrated stove with a cooking device and a method for drying an inner pot thereof. Background Art

[0002] The working principle of cooking devices with steaming function, such as steam ovens, steam-bake combination machines and microwave steam-bake combination machines, is mainly to heat and steam food by filling the inner pot with steam. Some steam cooking devices use external steam generators to supply steam, while others use built-in steam generators to supply steam.

[0003] After cooking, some steam will remain in the inner pot. In this way, not only will the steam in the inner pot rush directly to the user when the door is opened, thus causing a bad user experience, but also after the steam condenses, the condensed water will accumulate in the inner pot. If it is not used for a long time, it will not only cause the relevant parts to be corroded, affecting the service life, but also breed a large number of bacteria, thus causing safety hazards. At present, there is a way to solve the above problem by extracting steam from the inner pot. For example, the Chinese invention patent with application number CN201810025623.2 (publication number CN110025227A) discloses an oven with automatic dehumidification and drying function, which includes a cooking chamber, characterized in that it also includes: a dehumidification device, arranged on the outer wall of the cooking chamber, the dehumidification device includes a rotating member and a driving structure for driving the rotating member to rotate; a through hole, which is opened on the outer wall of the cooking chamber to accommodate the rotating member; and the rotating member exposes its partial surface to the inside or outside of the cooking chamber in rotation during the rotation of the through hole; a water storage box, which is arranged below the rotating member. This patent realizes drying of the condensed water in the cooking chamber by pumping the condensed water out of the cooking chamber. However, this method requires condensing the steam first and then pumping it out of the cooking chamber, and the drying efficiency is poor. Summary of the invention

[0004] The first technical problem to be solved by the present invention is to provide an integrated stove with a cooking device having high exhaust efficiency in view of the prior art.

[0005] The second technical problem to be solved by the present invention is to provide an integrated stove with a cooking device having high drying efficiency in view of the prior art.

[0006] The third technical problem to be solved by the present invention is to provide a method for drying the inner pot of an integrated stove with high drying efficiency in view of the prior art.

[0007] The technical solution adopted to solve the first technical problem mentioned above is: an integrated stove with a cooking device, comprising a cooking device and a stove arranged above the cooking device, the cooking device comprising an inner pot, and the above-mentioned stove comprising a stove shell, characterized in that the inner pot is provided with a main exhaust pipe connected to the interior of the inner pot and at least one branch exhaust pipe fluidly connected to the interior of the inner pot, the branch exhaust pipe is provided with a control valve for opening and closing the branch exhaust pipe, and the above-mentioned stove shell is provided with an exhaust port, and the main exhaust port of the main exhaust pipe and the branch exhaust port of the branch exhaust pipe are respectively fluidly connected to the exhaust port of the above-mentioned stove shell.

[0008] The technical solution adopted to solve the second technical problem is as follows: a hot air baffle with an air inlet and an air outlet is provided in the inner pot, and the hot air baffle and the back plate of the inner pot form a hot air chamber, a hot air blower is provided in the hot air chamber, and a ring-shaped back heating pipe is provided around the outer periphery of the hot air blower. The hot air blower is a dual-speed hot air blower, and when the hot air blower is in a low-speed gear, the control valve is closed, and when the hot air blower is in a high-speed gear, the control valve is opened. In this way, in the steaming mode, the hot air blower is in a low-speed gear, and each control valve is closed, and the steam in the inner pot is sucked into the hot air chamber through the rotation of the hot air blower for reheating, and the excess steam is discharged from the main exhaust pipe; after the steaming process is completed or before the steaming process is completed, the hot air blower is adjusted to a high-speed gear, and each control valve is opened, and the steam in the inner pot is sucked into the hot air chamber and quickly discharged through the main exhaust pipe and two branch exhaust pipes.

[0009] In order to further reduce the condensation of the residual steam in the inner pot into liquid water after the steaming is completed, a top heating tube is arranged on the lower surface of the top wall of the inner pot.

[0010] The steam used for heating in the cooking device can be generated in a variety of ways, and currently an external steam generator is generally used. A heating plate is provided at the bottom of the inner pot described in the present invention, and a water inlet is provided on the inner pot. The water inlet is connected to a water inlet pipe connected to a water inlet pump, and the water inlet pipe is provided with a solenoid valve for opening and closing the water inlet pipe. The water inlet pipe is connected to the water outlet of the water tank, and the water in the water tank enters the water inlet pipe, and the water in the water inlet pipe enters the inner pot through the water inlet. The heating plate heats the water in the inner pot to generate steam, and the generated steam is used to heat the food. At the same time, after the steaming process is completed, heating the bottom of the inner pot by the above-mentioned heating plate can effectively evaporate the condensed water remaining on the inner bottom surface of the inner pot.

[0011] Preferably, the stove shell comprises a bottom plate with an upper opening and a panel covering the bottom plate opening, the inner cavity of the stove shell is formed between the two, and the exhaust port is provided at the rear side of the panel, so as to effectively avoid the influence of the exhaust gas on the user's operation, thereby improving the user's experience.

[0012] In order to minimize the flow path of the airflow in the main exhaust pipe and the branch exhaust pipe, thereby further improving the exhaust efficiency, the main exhaust pipe and the branch exhaust pipe are both arranged on the back side of the inner liner, an exhaust hole is opened on the back plate of the inner liner, and a first air inlet and a second air inlet are opened on the bottom wall of the chassis, respectively. The main air inlet of the main exhaust pipe is connected to the exhaust hole, and the main exhaust port of the main exhaust pipe is connected to the first air inlet, the branch air inlet of the branch exhaust pipe is connected to the diversion port opened in the main exhaust pipe, and the branch exhaust port of the branch exhaust pipe is connected to the second air inlet. The airflow in the liner enters the main exhaust pipe through the exhaust hole and then is diverted to each branch exhaust port through the diversion ports on both sides. In this way, only one exhaust hole needs to be opened on the inner liner, thereby ensuring the airtightness of the inner liner and improving the exhaust speed of the inner liner.

[0013] In order to prevent the exhaust gas from running around inside the stove shell and the external exhaust gas flow containing water vapor, which is directly discharged into the stove shell and causes corrosion to the parts of the stove, an exhaust cavity is provided in the chassis, which is respectively connected to the main exhaust pipe and the exhaust port and the branch exhaust pipe and the exhaust port.

[0014] The above-mentioned exhaust cavity can be implemented in a variety of ways. Preferably, an exhaust box is provided in the stove shell, the above-mentioned panel cover is provided on the opening of the exhaust box to enclose the exhaust cavity, and the above-mentioned exhaust port is opposite to the opening of the exhaust box up and down, and a first inlet and a second inlet are respectively provided on the bottom wall of the exhaust box, and the edges of the first inlet and the second inlet respectively extend vertically downward to form a first joint and a second joint, and the first joint and the second joint respectively pass through the above-mentioned first air inlet and the second air inlet to be exposed to the chassis and are respectively connected to the main exhaust port of the main exhaust pipe and the branch exhaust port of the branch exhaust pipe.

[0015] The technical solution adopted to solve the third technical problem is: a method for drying the inner pot of the integrated stove as described above, characterized in that it comprises the following steps:

[0016] S1: Before the steaming process is completed, the water inlet pump and the solenoid valve are turned off, the water inlet to the inner pot stops, the heating plate continues to work, and the back heating tube and the top heating tube are turned on respectively;

[0017] S2: Turn on the hot air blower and adjust it to high speed;

[0018] S3: Open the above control valve to exhaust the main exhaust pipe and the branch exhaust pipe at the same time.

[0019] Preferably, 3 minutes before the steaming process is completed in step S1, the water pump and the solenoid valve are turned off and the heating tubes are turned on.

[0020] Compared with the prior art, the advantages of the present invention are that when the cooking device is in the steaming process, all control valves are closed, and the airflow in the inner pot passes through the main exhaust pipe, thereby preventing the steam in the inner pot from being discharged too quickly during the steaming process and affecting the steaming cooking efficiency. After the steaming process is completed, steam will remain in the inner pot. If the steam in the inner pot is not processed, the condensed water will accumulate in the inner pot after the steam condenses, which will not only corrode the relevant parts in the cooking device, but also cause a large number of bacteria to breed, thereby posing a safety hazard. Therefore, in the present invention, at least one branch exhaust pipe is also provided on the inner pot. After the steaming process is completed, the branch exhaust pipes can be opened at the same time, and the main exhaust pipe and the branch exhaust pipes can be exhausted at the same time, thereby improving the exhaust efficiency.

[0029] The present invention is further described in detail below with reference to the accompanying drawings.

[0030] like Figures 1 to 8 As shown, an integrated stove with a cooking device includes a cooking device 102 with a steaming function and a stove 101 arranged above the cooking device 102, the cooking device 102 includes an inner pot 1, and the stove 101 includes a stove shell 100, the stove shell 100 includes a bottom plate 1002 with an upper opening and a panel 1001 covering the opening of the bottom plate 1002, and the inner cavity of the stove shell 100 is formed between the two.

[0031] Furthermore, the inner pot 1 is provided with a main exhaust pipe 21 connected to the inner pot 1 and two branch exhaust pipes 22 respectively connected to the inner pot 1 by fluid, and each branch exhaust pipe 22 is provided with a control valve 5 for opening and closing the corresponding branch exhaust pipe 22. The stove shell 100 is provided with an exhaust port 1003, and the main exhaust port 211 of the main exhaust pipe 21 and the branch exhaust port 221 of the branch exhaust pipe 22 are respectively connected to the exhaust port 1003 of the stove shell 100 by fluid. In this way, when the cooking device 102 is in the steaming process, each control valve 5 is closed, and the airflow in the inner pot 1 is discharged through the main exhaust pipe 21, so as to avoid the steam in the inner pot 1 being discharged too quickly during the steaming process and affecting the steaming cooking efficiency. After the steaming process is completed, steam will remain in the inner pot 1. If the steam in the inner pot 1 is not processed, the condensed water will accumulate in the inner pot 1 after the steam condenses, which will not only corrode the relevant components in the cooking device 102, but also cause a large number of bacteria to grow, thereby causing safety hazards. Therefore, in the present invention, two branch exhaust pipes 22 are also provided on the inner pot 1. After the steaming process is completed, the branch exhaust pipes 22 can be opened at the same time, and the main exhaust pipe 21 and the two branch exhaust pipes 22 can be exhausted at the same time, thereby improving the exhaust efficiency.

[0032] In order to reduce the condensed water generated by the condensation of steam in the inner pot 1, a hot air baffle 31 with an air inlet and an air outlet is provided in the inner pot 1. The hot air baffle 31 and the back plate of the inner pot 1 form a hot air chamber 30. The hot air chamber 30 is provided with a hot air blower 3. The outer periphery of the hot air blower 3 is provided with an annular back heating pipe 32. When the hot air blower 3 rotates, the steam remaining in the inner pot 1 is sucked into the hot air chamber 30, and the back heating pipe 32 reheats the sucked steam, thereby avoiding the condensation of the steam in the inner pot 1. Further, the hot air blower 3 is a dual-speed hot air blower, that is, the hot air blower 3 has two gears of high speed and low speed. In this steaming mode, the hot air blower 3 is in a low-speed gear, the control valves 5 are closed, the steam in the inner pot 1 is sucked into the hot air chamber 30 for reheating through the rotation of the hot air blower 3, and the excess steam is discharged from the main exhaust pipe 21; after the steaming process is completed or before the steaming process is completed, the hot air blower 3 is adjusted to a high-speed gear, the control valves 5 are opened, the steam in the inner pot 1 is sucked into the hot air chamber 30 and then quickly discharged through the main exhaust pipe 21 and the two branch exhaust pipes 22.

[0033] In order to further reduce the condensation of residual steam into liquid water in the inner pot 1 after steaming, and to further promote the heating and evaporation of the condensed liquid water in the inner pot 1, a top heating tube 8 is arranged on the lower surface of the top wall of the inner pot 1.

[0034] In addition, the steam used for heating in the cooking device 102 can be generated in a variety of ways, and currently an external steam generator is generally used. In this embodiment, a heating plate 4 is provided at the bottom of the inner pot 1, and a water inlet (not shown) is provided on the inner pot 1. The water inlet is connected to a water inlet pipe 64 connected to a water inlet pump 61, and a solenoid valve 62 for opening and closing the water inlet pipe 64 is provided on the water inlet pipe 64. The water inlet pipe 64 is connected to the water outlet of the water tank 63, and the water in the water tank 63 enters the water inlet pipe 64, and the water in the water inlet pipe 64 enters the inner pot 11 through the water inlet. The heating plate 4 heats the water in the inner pot 1 to generate steam, and the generated steam is used to heat the food. At the same time, after the steaming process is completed, the condensed water remaining on the inner bottom surface of the inner pot 1 can be effectively evaporated by heating the bottom of the inner pot 1 through the heating plate 4.

[0035] The exhaust gas from the main exhaust pipe 21 and the branch exhaust pipes 22 is first discharged into the range housing 100, and then discharged through the exhaust port 1003 on the range housing 100. Preferably, the exhaust port 1003 is provided at the rear side of the panel 1001 of the range housing 100, so as to effectively avoid the influence of the exhaust gas on the user's operation, thereby improving the user's experience. In order to shorten the flow path of the airflow in the main exhaust pipe 21 and the branch exhaust pipe 22 to the greatest extent, thereby further improving the exhaust efficiency, preferably, the main exhaust pipe 21 and the branch exhaust pipe 22 are both arranged on the back side of the inner tank 1, and an exhaust hole 11 is opened on the back plate of the inner tank 1, and a first air inlet 1002a and two second air inlets 1002b are respectively opened on the bottom wall of the chassis 1002, the main air inlet 212 of the main exhaust pipe 21 is connected with the exhaust hole 11, and the main exhaust port 211 of the main exhaust pipe 21 is connected with the first air inlet 1002a, and the left and right sides of the air inlet end of the main exhaust pipe 21 are respectively provided with diversion ports 210, and the branch air inlet 222 of each of the branch exhaust pipes 22 is connected with the corresponding diversion port 210, and the branch exhaust port 221 of each branch exhaust pipe 22 is connected with the corresponding second air inlet 1002b. The airflow in the inner liner 1 enters the main exhaust pipe 21 through the exhaust hole 11 and is then diverted to each branch exhaust pipe 22 through the diversion ports 210 on both sides. In this way, only one exhaust hole 11 is required on the inner liner 1, thereby ensuring the air tightness of the inner liner 1 and increasing the exhaust speed of the inner liner 1.

[0036] In order to prevent the exhaust stove shell 100 from running around inside the stove shell 100 and the external exhaust flow contains water vapor, which will corrode the parts of the stove 101 if it is directly discharged into the stove shell 100, an exhaust cavity 70 is provided in the chassis 1002, and the exhaust cavity 70 is respectively connected to the main exhaust pipe 21 and the exhaust port 1003 and the branch exhaust pipe 22 and the exhaust port 1003. That is, in this embodiment, the gas in the main exhaust pipe 21 and the branch exhaust pipe 22 is first discharged into the exhaust cavity 70, and then discharged to the outside through the exhaust port 1003. The exhaust cavity 70 can be implemented in a variety of ways. In the present embodiment, an exhaust box 7 is provided in the stove shell 100. The panel 1001 is covered on the opening of the exhaust box 7 to form the exhaust cavity 70. The exhaust port 1003 is opposite to the opening of the exhaust box 7 in upper and lower directions. A first inlet 71 and a second inlet 72 are respectively provided on the bottom wall of the exhaust box 7. The edges of the first inlet 71 and the second inlet 72 extend vertically downward to form a first joint 711 and a second joint 721. The first joint 711 and the second joint 721 respectively pass through the first air inlet 1002a and the second air inlet 1002b to be exposed on the chassis 1002 and are respectively connected to the main exhaust port 211 of the main exhaust pipe 21 and the branch exhaust port 221 of the branch exhaust pipe 22.
